The first CCP holder we made solved a problem. It kept the sensor from leaking and making the bike run rich. The new holder is designed for performance. The problem is till solved but now changes are there to focus on performance. A new shape and internal diameters strengthen the pressure signal to the ecu. This sharpens throttle response and creates more accurate fueling.
Also this one is small enough to let you use the stock plastic mud cover
